There is no present tense. Think of yourself watching a kid bouncing a basketball. By the time the sound has reached you and by the time your brain has interpreted the visuals, trillions of neutrinos have already passed through your body, all kinds of radiations have affected you, and who knows what kind of dark matter / dark energy (which humans have yet to understand and measure) have gone through your body as well. Everything you think is present is really the past, just like looking at stars in the night sky; you are looking into the past. Present tense only exists in languages. Stupid slow humans... List is digs.

Not really...because if the only thing that makes something that is perceived as "in the present" actually "in the past" is the delay of perception versus action, then your perception of what is present actually BECOMES the present.

Sure, if the sun were to die out right now, just disappear, it would take us three minutes to perceive what had happened...but that would still mean that, to us, the sun would have simply disappeared, even if it was actually three minutes later, because we weren't where the sun was, and therefore cannot perceive "the present" from the sun's perspective.

That's why time is an irrelevant concept: because our perception can change what time is.
